Since -4 is the least integer in list K, then 7 is the largest integer in that list. Thus the range of the positive integers in the list is 7-1=6.

Answer: B.

No, the positive integers within the list are {1,2,3,4,5,7} for which the range is 7 - 1 = 6

Solution:

Set K = ( -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7)
Range is defined as the highest value of f(x) and the lowest value of f(x). Over here the range will be 7 - (-4) = 11.

Try making a graph of the set K and see what is the difference between the maximum value and the minimum value.

The set is {-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}. The question asks to find the range of the POSITIVE integers in the list.

The range of the POSITIVE integers in the list is {largest} - {smallest} = 7 - 1 = 6.

Hope it's clear.

Oh! I misread the positive numbers.
Then the range is 7 - 1 = 6

Simple one. However, the only thing to notice in this question is "range of the positive integers". You miss this and you are gone :P

numbers are -4,-3,-2,-1,0,1,2,3,4,5,6,7

range of positive numbers = 7-1= 6

note: zero is neither positive nor negative. it is neutral.
